摘要： A full-color display and techniques for fabrication thereof are provided. The display includes first and second continuous independently addressable organic emissive layers disposed over a single substrate or between two substrates or portions of a flexible substrate. The use of continuous emissive layers of a limited number of colors allows for a relatively high resolution display to be achieved without the use of fine metal masks or similar components.

摘要： A flexible AMOLED display is disclosed including an OLED stack having an anode layer, a cathode layer and an organic light emitting layer between the anode layer and the cathode layer. A backplane includes a substrate, a plurality of bus lines, and a thin film transistor array. A permeation barrier layer is positioned between the OLED stack and the backplane, and a plurality of vias connect the OLED anode layer to the backplane thin film transistor array. In one embodiment, a neutral plane of the AMOLED display crosses the permeation barrier. In one embodiment, the thickness of at least a portion of the bus lines is greater than the thickness of the cathode layer. A method of increasing the flexibility of an AMOLED display is disclosed. A method of assembling a flexible AMOLED display under a processing temperature of less than 200 degrees Celsius is also disclosed.

摘要： Devices and techniques for fabricating such devices are provided, which include an optical system having a combined permeation barrier and circular polarizer. The optical system is relatively thin and flexible, thereby allowing for OLED displays and similar devices that reduce glare while being suitable for use in flexible displays and similar devices.

摘要： Systems, devices, and techniques are provided for operating a display and/or an illumination source based upon the direction of a user's gaze and/or a desired illumination level in a monitored area. One or more elements may be controlled with sensor input and application lighting preferences. For example, when a user receives a video call, light may be activated to illuminate their face. When the user is looking at the display, the display will be at the brightness necessary for the lighting conditions. When the user looks away from the screen, the screen may dim further and the lighting elements for the desk can brighten. Similarly, embodiments may adjust the lighting in a monitored location based upon lighting levels identified in other areas.

摘要： Described herein are display devices having architectures with a reduced number of external connections from the display to the external electronics, which allows for an increase in the pitch of the external connections, thereby improving reliability and flexibility, and reducing costs. The architecture of these devices is based on using multiplexers to connect external source lines to the individual display column lines. Accordingly, data signals can come into the display on a reduced number of external source lines as compared to the number of display column lines. The architecture allows for high-reliability, rugged contacts to a small-sized display by avoiding the need for high resolution interconnects.

摘要： An OLED panel having a plurality of OLED circuit elements is provided. Each OLED circuit element may include a fuse or other component that can be ablated or otherwise opened to render the component essentially non-conductive. Each OLED circuit element may comprise a pixel that may include a first electrode, a second electrode, and an organic electroluminescent (EL) material disposed between the first and the second electrodes. Each of the OLED circuit elements may not be electrically connected in series with any other of the OLED circuit elements.

摘要： Full-color pixel arrangements for use in displays and other devices, and devices including the same, are provided. The pixel arrangement includes a patterned electrode layer including multiple electrodes, a patterned emissive layer disposed over the electrode layer, a blanket organic emissive layer disposed over the patterned emissive layer, a second electrode layer disposed between the organic emissive layers, and a third electrode layer disposed over the second blanket organic emissive layer. Electrodes within each of the electrode layers are individually addressable.
